We present a case of moderately differentiated neuroendocrine carcinoma of the larynx. These tumors represent 0.6% of all laryngeal carcinomas. Histological diagnosis requires the use of immunohistochemical methods, the tumoral cells presenting positivity for epithelial markers (cytokeratin) and neuroendocrine markers (chromogranin). Clinically, their location is supraglottic and they affect mainly males between the 6th-7th decades of life. The prognosis is better than that of squamous carcinoma or adenocarcinoma. The differential diagnosis must be made with granular cell tumor and paragangliomas.

D018278 Carcinoma, Neuroendocrine A group of carcinomas which share a characteristic morphology, often being composed of clusters and trabecular sheets of round "blue cells", granular chromatin, and an attenuated rim of poorly demarcated cytoplasm. Neuroendocrine tumors include carcinoids, small ("oat") cell carcinomas, medullary carcinoma of the thyroid, Merkel cell tumor, cutaneous neuroendocrine carcinoma, pancreatic islet cell tumors, and pheochromocytoma. Neurosecretory granules are found within the tumor cells. (Segen, Dictionary of Modern Medicine, 1992) Carcinomas, Neuroendocrine,Neuroendocrine Carcinoma,Neuroendocrine Carcinomas
